v1.2 released. Improved how noise is detected and processed. Added a "Removed sound" tab so you can hear exactly what was taken out.
Added lossless WAV download.

Drag & drop or click to select the audio you want to clean. Supports MP3, WAV, OGG and other major formats.
The browser finds moments where the waveform spikes (clicks) and repairs only those few milliseconds, either by interpolating from the surrounding waveform or by lowering them to the surrounding level. Everything runs on your device.
Switch between "Original", "Processed" and "Removed sound" at the same position. Red marks on the waveform show the processed spots.
Download the result as WAV (lossless) or MP3.
No sign-up. No usage limits. All features are free.
Audio is never uploaded. All processing happens in your browser.
Unlike noise reduction for steady noise, it detects short clicks and fixes just those moments. Nothing else is touched.
Processing runs at the original sample rate, and the waveform outside the detected milliseconds is left unchanged.
Short "tick" or "smack" sounds made when the mouth opens or the lips part. Most last a few milliseconds and stand out in quiet narration or a cappella singing.
It works best on short, sharp clicks between or inside words. Wet mouth sounds that blend into the voice itself (saliva, tongue bursts) cannot be told apart from speech and may remain. Background noise such as air conditioning is out of scope.
It spots momentary anomalies from the spikiness of the waveform (kurtosis); anything up to 3 ms is interpolated from the surrounding waveform, longer events are lowered to the surrounding level. This is the classic "de-click" idea. No AI model is used.
Reduces mouth clicks in video and e-learning narration so it is easier to listen to.
Fixes only the detected mouth clicks between phrases in quiet singing.
Reduces the mouth clicks that close-mic recording tends to pick up. For background noise, use our sister tool Shizuka.
Processes only the moments where unintended clicks are detected. Not everything disappears, so compare and adjust.
Yes, completely free. No sign-up or login, and no usage limits.
No. All processing happens in your browser. Your audio is never sent to a server.
Input supports MP3, WAV, OGG, M4A, FLAC, WebM and any format your browser can play. Output is WAV (lossless) or MP3 (192 kbps).
AI noise reduction targets steady noise such as air conditioning and barely affects clicks of a few milliseconds. Sawayaka detects clicks and fixes just those moments, and does nothing for background noise. For background noise, use our sister tool Shizuka.
Yes. It processes at the original sample rate and leaves the waveform outside the detected milliseconds unchanged, so quality is essentially preserved. At higher strengths, however, detection can touch parts of the voice.
Strong settings can affect plosives (p/t/k). Check the "Removed sound" tab for any voice in what was removed, and go down one step if you hear some.
Yes. Left and right channels are processed independently, since clicks often appear on only one channel.
Yes, directly in iPhone and Android browsers with no app to install. For long audio, keep within a few minutes due to memory.
Audio is never sent to a server. Everything runs in your browser, so even unreleased narration or music can be declicked safely.
Load major formats in your browser and export as WAV (lossless) or MP3 (192 kbps). Lip-noise removal works regardless of format.
Detects short clicks between and inside words and processes only those spots. Wet mouth sounds overlapping the voice may remain, so compare and choose the strength by ear.
With Chrome, Edge, Safari or Firefox it runs on Windows, Mac, iPhone and Android with no installation.
Sawayaka specializes in short clicks. For steady background noise such as air conditioning, use the AI noise remover Shizuka; for mouth clicks, use Sawayaka.
